WebApr 2, 2015 · However note that a crystal filter is likely to have a bandwidth of a couple of kilohertz, and a single crystal may have even less, while a ceramic filter at 10.7 MHz will have a bandwidth about 200 kHz. So depending on the bandwidth you need, (e.g. you need about 200kHz to receive FM audio) the crystal filter most likely won't do what you want. bizrate surveys review https://beyonddesignllc.net
